How to apportion the amount of NICs paid between tax years: Adjusting the employee’s NI account
Once you have calculated, as per NIM07071, the amounts of:
earnings; and
primary NICs
to be re-allocated, you will need to amend the relevant postings on the employee’s NI account on NIRS2. Do this:
in accordance with current guidance and procedures; and
by making the necessary adjustments as “employee only”.
So, using the figures in the example at NIM07071, you would:
for the 2021/22 tax year, increase the amounts of earnings and primary NICs by £1395.00 and £77.28 respectively; and
for the 2022/23 tax year, reduce the amounts of earnings and primary NICs by the same amounts.
